Similar letters of reference indicate correslponding parts inthe figures;

eferring to the drawings: A designates thefframe of the machine, on which is mounted the driving shaft B to which power is communicated in any suitable manner. 'G designates a countershaft which is mountedon-the frame A and geared with said shaft Bjas at Dor other suitable means.

Connected with-said shaft C are the weighted arms Eon the proper ends of which are mounted the connecting rods F with which latter is pivotally connected the arms G.

' Mounted on the table of the frame are the plates H in which are the downwardly curved slots J, the same receiving the. rollers K, the walls of said slots thus guiding said rollers, whereby they travel in a circular direction thereof, said rollers K being mounted on the arms G intermediate of the ends L designates a downwardly curved horn or bed which occupies-a position in the longitudinal direction of the machine at the center thereof, 1 it being elevated above the guide plates H and sustained at one end, at present, toward the driving shaft B, by the standard M which rises from the table of the frame A.

Pivotally mounted on the ends of the arms G by the shaft G are the heads N, the same forming bearings for the shafts P, Q, said shaftsbeing eccentric in saidhea'd. On the shaft P are the bending rollers R and on the shaft Q are the bending rollers S, said rollers R, S, .occupyin a position above the bed L,

it being notice that the face of the roller R is conical as shown in Figs. 4 and 7 and the face of the roller S is formed with an undercut groove having one wall inclined as shown in" Figs. e and6.. I Connected with the heads N are the arms T on which are adjustably fitted the weights U, itbeing noticed that said heads are freely mounted on the arms G, whereby they may overturn and thus bring either of the rollers R, S, adjacent to the bed L for purposes to be hereinafter explained;

Connected "with the sides of the arms G are the segmental arms V on the ends 01 l which are bolts W, N, which project in such a manner respectively toward the upper and lower sides of the heads N as to cause the overturning of the latter as will be hereinafter described.

On the outer ends of the bed L are plates or bolts X which are fitted in openings in said bed so as to be capable of motion in a lateral direction so as tov project from said bed as shown in Figs. 1 and 5 and form stops as will be hereinafter explained, said plates being held in outward or operative position by means of the springs X which bear against said plates and a fixed member of the head. On the sides of the bed are the guiding wings Y which are secured thereto by the blocks Y and bolts Y or other suitable means, said blocks forming stops. On the upper side of the bed is a resilient stop formed of the shoulder Z which is carried by the spring plate Z, one end of which is connected with said bed. as at Z the latter having a recess Z therein to permit the stop to lower thereinto, said bed also containing a spring Z which bears against said stop to raise the same to normal position.

Referring to Figs. 13, 14, 15, 16 and 17, L designates an upwardly curved or circu- ,lar bed and H designates plates with upwardly curved slots or recesses J therein, said slots receiving the guide rollers hi, whose bearings are on a traveler K and have pivotally connected with them the )itmen E which receive motions similar to t 1e pitmen F. N designates heads which are pivotally mounted on said. traveler and have mounted on them the shafts P, Q, on which are respectively secured the bending rollers R, S, which are similar in contour to those of the rollers R, S. To the sides of the heads l are secured the arm V which carries on its ends the bolts N for purposes similar to the bolts Wf In the heads N are slots N 2 which freely receive the rollers h which are mounted on the links N3 the latter being pivotally mounted as at a and connected by the handle whereby by proper operation of the latter, said heads in. y be overturned as will be apparent on reference to Figs. '14 and 15.

Referring to Fig. 11 it will be noted that the heads N have adjustably mounted thereon the bearing blocks N which have the elongated slots N through which pass the bolts N and bolts N adjustable in cleats N on the heads bearing against opposite ends of the bearing blocks and provided with jam nuts N serve to adjust the shafts P and Q and their rollers R and S.

In Figs. 14 and 15 the travelers K are provided with movable blocks N in which are mounted the shafts P and Q, bolts and nuts being provided as shown to permit of adjustment of the said shafts and their rollers in a similar manner to that above do- I scribed In connection with l 1g. ll.

ihe operation is as l'ollows: lhe plates ol metal of which an elbow is to be constructed have their edges l'ornied with tongues and grooves which are adapted to locl: each other as shown in Fig. 5. 'ihose of such plates forming three sides of said elbow are connected as shown in said ligures and placed on the bed l3, so that the edge of the top plate abuts against the shoulder Z said top plate being concave and the edges ol the side plates enter between the wings Y and are held thereby against the blocks Y. The front edges of the side plate abut against the latches or plates X and thus the several connected plates as shaped rest firmly on the bed. Power is now applied to the shalt ll and consequently to the shalt (.1, whereby inotions a re imparted to the arms ill, the pitinen F and a1 .is G, thelatterthencarrying the rollers ll through the curved slots or ways .l and advancing the head lx' thereby the rollers 8 ben r downwardly against the upwardly projecting scams S, S ol' the three plates and owing to the conieally grooved or recessed laces ol said rollers, said seams are bent latm'ally as shown in l'ig. l). \(hen the arms (l have completed their stroke, the bolts l" on thc 5 bear against the adjacent sides ol the head N and turn the same on the shalt U in the direction of the arrow l Fig. 2 when, as said. head is out ol' its center of gravity, the weighted arlns "f quickly overturn said head and place the rollers 5 above and consequently the rollers ll. below, see Fig. b. The motions of the arns G are oscillatory to allow of the change of position ol the parts. The head is now carried backward and the rollers ll. are brought into contact with the laterally bent seai'ns l ig. 9, whereby owing to the inclined laces ol said rollers .li, the seams are pressed llat and tightly closed, the result being shown in l igs. It} and 20, it being evident that the three plates are now lir nly connected as one. "the latches or plates X are now drawn in, when the three-sided shape is slipped from the bed.

lt will be seen, that when the seams are subjected to the action ol either set of rollers, and the top plate accordingly depressed, the shoulder Z yiclds downwardly as the rollers pass over the place of its location, but quiclily rises as the rollers continue their motions so that said top plate re'nains pructically engaged by said shoulder. lt will be seen that when the head reaches its full return motion, it is engaged by the other bolt Y which presses against the same in the direction of arrow 2 and when said head again passes the center of gravity, it is over turned to its first position by the weight arm 'l, whereby the rollers S are below and the rollers ll above, the arms owing to their oscillations then changing from the position grooves of the side plates 'and'a'pplied'tothe shown in Fig. 3 to that shown in Fig.2, the a shaft which said pivotally machine then being stopped. :The plates H v mounted, an oscillating arm'carrying said are provided at oppositeends thereof with cushions or buflers which receive the blows or impact of the arms Tin their overturning motions. The fourthplate which is convex is now connected by its tongues withthe bedL said fourth late being on topof said bed, see Fig. 17, it eing firmly held down in said bed by the action of thesprings L see.

Fig. 13, which springs areconnecte'd with the underside ofthe bed and. contact with'and" now bear downwardly against theinner side of the lower plate as shown in sai'd'Fig. 17. Then the head N is advanced when the rollers'R engage with the top seams S formed by the upwardly projecting tongues and grooves and bend the same laterally as shown in Fig. 18. Then when the head has traveled to full extent in its advancingdirection, it is overturned by hand by the operation of the roller N and link N due to the handle N and, the rollers S bear downwardly against the bent seams and as the head makes its return motion, said seams are pressed down flat and closed see Fig. 19,

thus firmly connecting the side plates with the present top plate, and completing the connection of the four sided shape by hand to its first position, soas to repeat the operations named, the rollers R then being below. The latches X are now drawn back when the sha ed article shown in Fig. 21 may befen- Y tire y removed from the bed. c
